目的 探讨脉冲Nd:YAG激光及激光联合置管术治疗泪道阻塞性疾病临床疗效.方法 回顾性病例分析.应用Nd:YAG激光及激光联合置管术治疗泪道阻塞性疾病共472例514只眼.结果 (1)泪小管阻塞的留置U形硅胶管及留置硬膜外导管的治愈率分别为75％及70％,高于单纯YAG激光的治愈率31％,P＜0.05.(2)泪总管及鼻泪管阻塞留置U形硅胶管治愈率100％,高于单纯YAG激光的治愈率65％,P＜0.05.(3)泪囊炎留置U形管、留置硬膜外导管及逆行植入人工鼻泪管的治愈率分别为55％、60％、78％,明显优于单纯YAG激光治疗.结论 单纯YAG激光对于各种原因的泪道阻塞虽然疏通率均较高,但治愈率除泪总管、鼻泪管阻塞较好外,其他均不理想,特别是对于泪囊炎疗效较差.而激光联合植入其他引流管似可在一定程度上提高各种原因泪道阻塞的短期治愈率.
